Abstract: An anti-static flash spinning composite non-woven fabric and a preparation method thereof are provided. The preparation method includes the following steps, S1: taking anti-static functional masterbatch and a first polymer as spunbond raw materials, obtaining spunbonded fibre with the spunbond raw materials by a spunbond process, and forming a spunbonded fibre web by aggregating the spunbonded fibre; S2: taking a second polymer as a raw material, obtaining a flash spinning fiber web sheet by a flash spinning process; forming a flash spinning fiber layer by laying the flash spinning fiber web sheet on the spunbonded fibre web to obtain a composite fiber web; S3: performing a cold pressing treatment and a hot rolling treatment on the composite fiber web sequentially, causing the spunbonded fibre web to form a spunbond layer and causing the flash spinning fiber layer to form a flash spinning layer.

Abstract: The disclosure relates to the technical field of nonwoven fabric manufacturing, in particular to a novel antibacterial breathable fabric and a preparation method thereof. The preparation method includes following steps: S1, surface hot rolling treatment: performing the surface hot rolling treatment on a fiber mesh layer, where a lower surface of the fiber mesh layer is supported by a flexible belt, and a hot rolling member contacts and hot rolls an upper surface of the fiber mesh layer, so as to prepare the fiber mesh layer with fibers on the upper surface thermally bonded and fibers on the lower surface fluffy; and S2, spunlace processing treatment: performing the spunlace processing treatment on the lower surface of the fiber mesh layer prepared in the S1; and the flexible belt is made of a high-temperature resistant flexible material.

Abstract: A flash spinning method for preparing non-woven fabrics based on microwave thermal fusion, a microwave thermal fusion device, and a non-woven fabric preparation device are provided. The flash spinning method includes: step S1, collecting filament bundles to form a non-woven fabric precursor, adding a microwave heating liquid to the non-woven fabric precursor; the microwave heating liquid being configured to absorb microwave energy and convert the microwave energy into thermal energy; and step S2, performing microwave heating on the non-woven fabric precursor containing the microwave heating liquid obtained in the step S1 to obtain a heated non-woven fabric, and performing a hot press forming treatment on the heated non-woven fabric to obtain a finished non-woven fabric. There is no temperature gradient in layers of the non-woven fabric precursor, thereby significantly improving the peeling strength of the finished non-woven fabric.

Abstract: The composite microporour filter material comprises a base-cloth layer, an upper adhesion layer attached to a top side of the base-cloth layer, and a lower adhesion layer attached to a bottom side of the base-cloth layer. The base-cloth layer is made of either polymide yarn base-cloth, polysulfoneamide yarn base-cloth, or polytetrafluoroethylene filament base-cloth. The upper adhesion layer is made of a mixture of polysulfoneamide short-staple and polymide short-staple; the lower adhesion layer is made of a pure polysulfoneamide short-staple. The upper adhesion layer and the lower adhesion layer are attached to two sides of the base-cloth layer by entangling which is adopted by needle punching, spunlacing or a combination thereof. The present filter material is temperature-resistant and corrosion-resistant and has features of a low manufacturing cost and the high filter precision.
